Specification 'of Letters Patent. Patented Mjay 19, 1914,

Application filed May 9, 1913. Serial No. 766,481.

To all'whowi it may concern Be-it known that I, Hnnanmr; MEYER, a

I citizen of the German Empire, residing at Barmen, Germany, have invented certain new and useful Improvements in Devices for Closing the Tapping-Openings of Smelting- Furnaces, of which the following is a speeification. v I

This invention relates. to a device for closing the tapping openings of smelting furnaces and consists in that the plug carrier, which is suspended from a link so as to be capable of oscillation, is guided in such a manner that the plug islowered to the heightof the tapping opening just prior to its insertion.

Figure 1 is a side elevation, illustrating the closing device attached to a furnace and in, its normal inactive position. Fig. 1 is a fragmentary horizontal section thereof, taken on the line l -1, Fig. 1. Fig. 2 is a side elevation of a furnace with the closing device attached and in position for closing siowing the tapping opening closed by said device.

a is the smelting furnace for metal, 6 is the tapping opening and c the tapping chain nel. In bearings d provided on the furnace the tapping o ening thereof. Fig. 3 is a '2 similar view a'is rotatably mounted a shaft e on which are secured a lever f and a link 9. The link p is at its free end provided with two cheeks A, between which and on a pivot 2' is mount ed the plug carrier is so as to be capable of oscillation.

Thecheeks la are provided With a number of holes m by means of which the pivot z for the plug carrier is can be adjusted. The cheeks h are in addition provided with the slots at in which screw bolts are provided transversely through the cheek It so that the distance of oscillation of the plug carrier [c can be suitably adjusted within the slots n. The headqr adapted for the reception of the plug is connected to the carrier is in a suitable detachablelmanner, so that it can be exchanged according to requirements.

the opposite end of the carrier is is adjustably mounted a weight g which tends to 5% press upward the head end of the carrier 7,-

when inserting the plug, so that it cannot come into contact with the stream of metal flowing from the tapping opening 6. Only justprior to the insertion of the plug into thetappin opening is the head end of the carrier 7:, y means of a rail 1- provided thereon, when this comes into contact with a suitable stop or guide 8 provided on the furnace or in any other suitable position, depressed against the action of the weight g and the ing (Fig. 3). The movement ofv the device -1s produced by the handlever t hinged to the lever f whereby the closing movement is pro- 'duced by means of a weight u provided on the lever f, the movement of the device into its initial position (Fig. 1) being produced by a weight 'w connected to the lever f by a rope v r Naturally a positive movement of the plug carrier can be effected by other means than those described, it is only of importance that the guide of the plug is such that it dips into the metal stream only just prior to its insertion into the tapping opening, whereby the certain, non-dangerous operation is obtained.

I claim: 1. A device for closing the tapping opening of smelting furnaces comprising: a link pivotally secured thereto above the opening;

plug guided into the tapping openan oscillatory plug carrier pivotally suspended therefrom; means to limit the oscillation of said plug carrier; means to lower said link and carrier; and means to engage said plug carrier to guide the same into the said tapping opening.

2. A device for closing the tapping'opening of smelting furnaces comprising: a link pivotally secured thereto above the opening; an oscillatory plug carrier pivotally sus pended therefrom; means to limit the oscillation of said plug .carriier; means to lower said link and carrier; and adjustable means to guide the same into the said tapping opening.

3 A device for closing the tapping opening of smelting furnaces comprising: a link pivotally secured thereto above the opening; an oscillatory plug carrier pivotally suspended therefrom; means to limit the oscillation of said plug carrier; means to lower said link and carrier; :1 member carried by said plug carrier, and a stop secured to said furnace adapted to be engaged thereby to guide the plug ca er into the said tapping opening.

l. A device for closing the tapping opening of smelting furnaces comprising 1 a link pivotally secured thereto above the opening; an adjustable, oscillatory plug carrier pivotally suspended therefrom; means to limit the oscillation-of sai plug carrier; means to lower said link and carrier; and nienns to engage said plug carrier to gufie the same into the said tapping opening.

5. A device for closing the tapping opening of smelting furnaces comprising: a; link pivotally secured thereto above the opening; an adjustable oscillatory plug carrier pivotally suspended therefrom, and an exchangeable heacl xnennted thereon for the reception of the plelg; means to limit the oscillation of said plug carrier; meensto lower said link and carrier; and means to engage said plug carrier to guide the some into the said tapping opening.

6. A device or closing the tapping opening of smelting furnaces comprising: a lin pivotally secured thereto above the opening; an adjustable, counterweightefi oscillatory plug carrier pivotally suspended therefrom, and adepte to be normally held above the surface of the metal stream from the furnsce; means to limit the oscillation of said plug carrier; means to lower said link and carrier; snrl means to engage ssiel ping eer- 25 rier to guiele'tiie opening 1 I v 7. A device for closingthe'tspping opening of smelting furnacgs compris ng: a, link pivotelly secured to the furnace; at levereonnected therewith, and a haml lever lilngefl to said lever; a closing weight mounted upon said lever; a plug carrier pivot-ally suspended from said link; adjustable means to limit the oscillation of said plug carrier; a member carried by said plug carrier; and a stop secured to said furnace eds ted to'be en gaged thereby to guide'the p ug carrier intothe said. tagsping opening when the hand lever is drawn downwardly. 4

In testimony whereof, I have signetl my name to this specification in the presence of two subscribing Witnesses.
